Rasgo de zónula anterior larga, lecciones aprendidas acerca de una infrecuente forma de cierre angular secundario: comunicación de un caso / Long anterior zonule trait, lessons learned about an uncommon form of secondary angle closure: A case report

Una mujer de raza negra de 62 años de edad que presentaba glaucoma crónico de ángulo estrecho no controlado en tratamiento con tres fármacos fue sometida a faco-esclerectomía profunda no perforante (facoEPNP) de su ojo izquierdo (OI). Durante la cirugía se puso de manifiesto que presentaba rasgo de zónula larga. Precisó goniopunción y desbridamiento de la ampolla posteriormente, presentando una sinequia de iris en la goniopunción que pudo ser reducida de forma conservadora. Este rasgo debe sospecharse en aquellos pacientes que presentan un ángulo estrecho combinado con un síndrome de dispersión pigmentaria. El manejo de la hipertensión ocular y el glaucoma que puede aparecer asociado a este rasgo no está protocolizado. En esta comunicación se reflexiona acerca de la mejor actuación ante esta infrecuente forma de glaucoma.(AU)

A 62-year-old black woman with uncontrolled chronic narrow-angle glaucoma on 3-drug therapy underwent phaco-non-perforating deep sclerectomy of her left eye. During surgery it was revealed that she had long zonule trait. She later required goniopuncture and conjuntival needling, presenting an iris synechia on the goniopuncture that could be reduced conservatively. Long anterior zonule trait should be suspected in those patients presenting with a combination of narrow angle and pigment dispersion syndrome. The management of ocular hypertension and glaucoma associated to this trait is not protocolized. This communication discusses on the best action in this rare form of glaucoma.(AU)

Aproximaciones a la epidemiología de la neuropatía óptica hereditaria de Leber en la comunidad autónoma de Madrid a través de una encuesta a los neuroftalmólogos / Approaches to the epidemiology of NOHL in the region of Madrid: Survey of neuro-ophthalmologists

Objective To estimate the epidemiology of Leber's optic neuropathy (NOHL) in the Region of Madrid. Material and methodsThe neuro-ophthalmologists who work at public hospitals of the CAM were interviewed by telephone. They were asked about the number of patients with NOHL that they had diagnosed during the time that they had been responsible for the neuro-ophthalmology department of that public hospital. The time worked and the population attended by the hospital were used to calculate the number of patient-years in follow-up by each center during the corresponding period. The basic information of each case (date of birth, mutation, and date of visual loss) was registered to avoid duplications. Results Our work estimates a global incidence of 2.34 cases for 10,000,000 inhabitants-year and a prevalence estimated from incidence of one case for each 106,682 inhabitants. This prevalence was very similar in all the studied areas and considerably lower than that reported by other studies. Conclusion This work constitutes the first approach to the epidemiology of this disease in Spain. The prevalence of NOHL in the region of Madrid is probably lower than that reported in the literature in other regions. The prevalence and the incidence were homogeneously low in the 26 studied areas. (AU)

Objetivo Estimar la epidemiología (incidencia y prevalencia) de la neuropatía óptica de Leber (NOHL) en la comunidad autónoma de Madrid (CM). Material y métodosLos neuroftalmólogos que trabajan en los hospitales públicos de la CAM fueron entrevistados telefónicamente. Se les preguntó por el número de pacientes con NOHL que habían diagnosticados durante el tiempo que han sido responsables de la consulta de neuroftalmología de ese hospital público. El tiempo trabajado y la población atendida por el hospital se utilizaron para calcular el número de habitantes-años en seguimiento por cada centro durante el periodo correspondiente y estimar la incidencia en cada área. La prevalencia estimada a partir de la incidencia (PEI) se calculó considerando que un paciente con NOHL vive unos 40 años con la enfermedad. Se registró la información básica de cada caso cuando estaba disponible (sexo, fecha de nacimiento, mutación, fecha de la pérdida visual) para evitar duplicaciones. Resultados Nuestro trabajo estima una incidencia global de 2,34 casos por cada 10.000.000 habitantes-año y una PEI de 1 caso por cada 106.682 habitantes. Esta prevalencia es inferior a la referida por otros estudios. Conclusión Este trabajo constituye la primera aproximación a la epidemiología de esta enfermedad en España. La prevalencia estimada de la NOHL en la CM es probablemente inferior a la reportada en la literatura en otras regiones. La prevalencia y la incidencia fueron homogéneamente bajas en las 26 áreas estudiadas. (AU)

Actualización clínica en nanoftalmos: características, enfermedades y complicaciones asociadas / Clinical update in nanophthalmos: Features, diseases and complications associated

El nanoftalmos es una condición congénita infrecuente del globo ocular que se caracteriza por un menor tamaño de los segmentos anterior y posterior en ausencia de una malformación ocular definida. Tradicionalmente se han descrito alteraciones anatómicas asociadas como una longitud axial corta, esclera engrosada, córnea con menor diámetro, cámara anterior estrecha y aumento de la relación entre el volumen del cristalino y el globo ocular. La causa se desconoce, aunque se han descrito múltiples mutaciones que podrían estar asociadas. En la actualidad, falta todavía una definición y una clasificación consensuada. Su relevancia clínica deriva de la asociación con múltiples afecciones oculares que pueden limitar la función visual como son hipermetropía elevada, ambliopía, glaucoma de ángulo cerrado, desprendimiento de retina y catarata. Asimismo, tanto la cirugía de catarata como la de glaucoma siguen constituyendo un desafío en estos ojos en los que el riesgo de numerosas complicaciones tanto intraoperatorias como postoperatorias es significativamente más elevado. El tratamiento del nanoftalmos tiene una doble orientación. Es preciso tratar las enfermedades asociadas y, además, reducir y controlar las complicaciones quirúrgicas. Esta revisión pretende realizar una actualización de lo publicado en los últimos años en relación con esta enfermedad. (AU)

Nanophthalmos is a rare congenital condition of the eyeball that is characterized by a smaller size of the anterior and posterior segments without associated ocular malformations. Typical features that have traditionally been described in these eyes are short axial length, thickened sclera, cornea with a smaller diameter, narrow anterior chamber, and an increased lens to globe volume ratio. However, at present, there is still a lack of recognized diagnostic criteria for nanophthalmos and a classification of its severity. Its clinical relevance stems from the increased risk of multiple ocular conditions, such as high hyperopia, amblyopia, angle-closure glaucoma, retinal detachment, and cataracts. Likewise, in relation to surgery in these eyes, there are particularities in cataract and glaucoma surgery and with a greater risk of associated intra- and postoperative complications. In this way, the treatment of nanophthalmos focuses on controlling the associated eye conditions and reducing and controlling surgical complications. This review aims to update what has been published in recent years regarding nanophthalmos. (AU)

Pathways between verbal bullying and oral conditions among school children.

PURPOSE: To investigate the direct and indirect pathways between verbal bullying and adverse oral conditions among school-aged children. METHODS: A cross-sectional survey was conducted with 8- to 10-year-old children, enrolled in public schools in Southern Brazil. Verbal bullying was collected by self-reports. Independent variables included sociodemographic characteristics (sex, age, household income, and caregivers' educational level) and oral conditions (anterior open bite, anterior teeth crowding, upper anterior diastema, large overjet, untreated dental caries, and PUFA index). The pathways between verbal bullying and the independent variables were analysed through structural equation modelling. RESULTS: 1369 children were included. The prevalence of verbal bullying was 26.2% (95% confidence interval [CI] 23.9-28.6%). Verbal bullying was directly influenced by large overjet (standard coefficient [SC] 0.13, P < 0.01), untreated dental caries (SC 0.63, P = 0.01) and PUFA index (SC 0.75, P = 0.02). Sex (SC - 0.005, P = .04) and age (SC - 0.006, P < 0.01) indirectly influenced verbal bullying via untreated dental caries. CONCLUSIONS: Verbal bullying was directly influenced by large overjet, untreated dental caries and PUFA index. Sex and age indirectly impacted verbal bullying through untreated dental caries.
